Application tiled January 2, 190B. Serial No. 408,866.

To all whom 'it may concern:

13e it known that I, PAUL G. WIEGERT, a resident `of Chicago, in they county of Cook and State of Illinois, have invented anew and useful Improvemnt'in Window Frames and Sashes; and I do hereby vdeclare the following to be a full, clear, and exact descri tion thereof. l

y invention relates to window frames and sashes Aand has special reference to metallic frames and sashes.

The'object of my invention is to form a cheap-.sinple and eiicient window frame and sash wlnchwill be entirely fire-proof in its construction and with a frame or casing Whichwill require less s ace in the thickness showing one side of the4 same. side elevation of thqlcwnter-balance for the of the building wall t an inthe ordinary approved forms by reason of its compactness, aswell as one which will dispense `with the lintels ordinarily used, an so provide a frame or' casing which will be of sufficient strength and Weight to furnish support 4for the masonry equlvalent to the lintels that are used for that purpose.

A still further object of my invention is to l ]provide for a construction of sash which w allowv for the clear play to avoid binding of the same in the frame, will be substantial and compact, and will have an equal bearing distributed along the same.

My invention consists, `generally stated,

-in the novel arrangement, construction Vand qomblnatlon of parts, as hereinafter morespecicall 4set forth and described and particular y pointed out in. the claims.

.To enable others skilled in the art to which my invention appertains to construct and luse m improved 'window frame and describe the same more fully, referring .tothe accompanying drawings, 1n which:

Like symbols of reference herein indicate like arts in each of the figures of the drawin s.

As il ustrated in said drawings 1, re: resents the window frame or casing wliic is formed of metal such as iron or steel and comcprises the side portions or jambe 2, the hea 3 and the sill 4. The side ortions or jambe 2 and head 3 are formed olloW and are each provided with the inner and outer sections 5 and A6, engaging with the masonry or brick Work A, said section 5 being of L- shaed' form, and said outer section 6 bein in t e form of ,achannel bar, preferably o rolled steel. These sections 5 and 6 are connected to each other at their upper adjoining and angular `cut ends through the brackets 7 and rivets S. The inner sections 5 of the jambe 2 and head 3 t over and against the end edges of the channel fian'ges 3 and are provided with a Z-shaped flange '9 thereon for forming the outer face -of the rarnejjl and extending to the masonry or brickwork A, and said sections and the outer seo, tions 6 are connected together by the screws 30 engaging said flange and the outer flange 3 of the channel forming said outer sections and by the screws 11 engaging the inner flan e 3"on said channel and a lug 12 on the inner sections 5. An inner face plate 13 fits over the inner flan e 3 on the sections 6 and over the edge of t e inner section 5 and is secured to said ilange b the screws 14. The sill 4 is alsoforrned ollow and oomprises the two sections 15 vand 16 which rest upon the masonry or brick-Work A b their flanges 1 7 and are connected togen 'ier .at their lower portions through said lianges by the bar 18 extending between the same and secured thereto by the screws 19. The section 15 is provided with the u p er face 20,' which is downwardly inclined in t e ordinary manner towards the outer end of said sec ion extending beyond the masonry or brickirl.: A, and the section 16 which forms the inno" face ofthe sillv 4 has a flange 21 extending over said upper face 20 and connected thereto by the screws 22.

Within the ranie 1 are the upper and lower sashes 23 which are formed of metal such as iron or steel, and are each composed of the `outer and. -inncr L-sha d sections 24 and 25 for forrnn f the hol ow incloscd framesfibereof. 'l le sections 24 and 25 for said frames 26 are connected together by by the rooved means of the boltsypr rivets 27 engaging the sides 28 of said sections and the opposing sides of each of said sections at the meeting rails of the frames 26 are provided with vertical portions 2U and the projecting portions 3() having the inclined ortions 31 and the vertical portions 32. rl e inclined ortions 31 fit over and under each other to lf)orm an overlappin f joint when the sashes 23 are in their closer positions, to thereby enable a substantially air tight connection to be formed at this oint, and braces 33 connect the two sides ofP the sashes 23 for strengthening the saine.

l he inner section 24 on the sashes 23 is provided with the projecting portion 36 thereon which extends inwardly rom the side 28 of said section and somewhat beyond the inner edge 35 on the section 25 on said sashes for forming a sto for the r'lass plate or licht 37 and said stop is braced a. rib 36 under the same and which abuts wit said side 28. 'Ihe plate or light 37 in these ireproof constructions is generally formed of wired glass and it is held in place-against said stop 36 by the )ins 33 inserted within said ed e 35 so that the putty 39 can be afterwards p aced against said light and edge to form the usual air tight connection.

The sashes 23 are radaplted to move within grooves 40 formed by t e `outer sections 5 on the jambs2 and head 3 and by the inner, outer and parting beads 41, preferably of rolled steel, which are placed in their usual positions and are secured to said sections by the screws 42.. Mounted loosel within the channel guiding boxes 42 set wit in the beads 4l on the jainbs 2 are the balls 43 which cxtend slightly beyond the said boxes and beads and are adapted to bear against the two side faces of the sashes 23 formed by the sections 24 and 25 thereof to form the ball bearings 44. These ball bearings 44 are laced at intervals and staggered along said lhces, and are so arranged to revolve within the guiding boxes 42 as to allow suflicient lay, for the same and will distribute an equal earing along jthe two side faces of the sashes 23.

rIhe outer side of the sashes 23 formed by the outer sections 24 of the same and facing the sections -5 of the jambs 2 are with the roller bearings 45`iihich are formed rollers 46 arranged at intern and through said sections 24 and d bead 47 formed jambe, so that vals Wi' ada ted to bear on a curve on t e said sections 6` of said said sashes willtravel freel in the grooves 40 of the jambs 2 throng said bearings. These rollers 46 arel mounted on shafts 48 formed in screw-shape, the inner sections 24 of the sas es 23 sand are journaled Ain bearings 49 formed' on said sectiene and the sections 25 of said sashes.

The sashes 23 are counterbalanced in the provide and theypass throughv 9i Leen.

movements within the grooves 40 in the lambs 2thro h the chains 50 at each side of said jambs an each connected to each outer face of said sashes by one of their ends through the screw pins 51, which are secured to the outer lfaces of the sections 25 of said t sashes and within grooves 52 formed by a lip l 53 on the sections 24 of said sashes and a` l shoulder 54 formed on said sections 25, so that said chains and the grooved pulleys 55 hereinafter described can be seated within said grooves in the movements of said sashes along the grooves 40. Each of the chains 50 pass over one of the pulleys 55 which are mounted within the ho low jambs 2 so as to extend through an openin section 6 of said jambs an into the grooves 40, and the two pulleys on one side of each of said jambe are loosely journaled on a shaft 57 madei'n the form of a screw-bolt and mountleed within bearings 58 formed on the inner face of said outer sections 6. The pulleys 55 i have a series f balls 59 within a seat 60 formed insee 'of the same, which holes are 'adapted tdengage with the shaft 57 to form a ball-bearing connection therewith for the easy movement of said pulleys and sashes 23 connected to one end of the chains 50 passing over said pulleys. The opposite ends of e chains 50 are each connected to one side of weight 61 through an eye 62, such weight being adapted to travel verticali within the hollow ortion of the jambs 2 by eng guided central y on a rod 63, and the inner sections 5 of said jambs are provided with a removable section 5 within the lower portions of the saine, which is held in place by one of the screws in the parting bead engaging with lugs 5" on said section 5 and extendi over the top and bottom ofsaid section 5' oraccess to the weights and their constructions in each of said jambs. This rod 63 is located centrally of said hollow portion, and is supported at its lower end in a bracket 64 formed on the inner face of the inner 'amb section 6 through a nut 65 engaging with the threaded lower end of said rod, while its upper end is bent toward said section, as at 66, and is secured to said section by the screws 67.

Between thev lower end of the weight 61 and the brackets 64 and fitting around the rod 63 through an opening through the saine is the bumper 68 which is formed of suitable flexible material, preferably rubber and is is formed during the 56 in the outer supported on the bracket 64. The weight B1.

ies

is placed against said bar and is securedto said iianges by the screws 72. The inner sections 5 have their anges 9 overlapping each other and are secured together by the screws 73, whichfscrews also extend into a bracket 74 fitting against the inner one of 'said anges for securing the same and inch p bracket also fits against the center flange ,7 0 l on the bar 69 for being secured thereto b the rivets 75, while such center flange wij` also act as a dividing wall for forming the ,hollow portions on each side of the same for the weights and their operating devices, as

, hereinbefore described. f

,When it is desired to use a transom in the frame or casing 1, such as is shown in Fig. 7, a hollow sill construction/76 is used between the sashes 23 and they head 3, which is.

formed of the top and bottom sections 77 -and 77 of substantially L-shape and secured together through ltheir. {langes-78 by screws 79 passing into lugs 80 on the main portions or odies of said sections. The body of the top. section 77 is provided with a shoulder 8l thereon around which a shoulder 831011 the bottom faceof the inner section on the frame for the transorn-82 engages, and with this exception and the upper face of the said frame being inclined, the two sections comprising said frame are substantially like thev sections 24 and 25 for the sashes 23. The

transom 82, as shown,4 is a tilting one and tilts on the hinge 84 connecting the same and the upper face of the sill 76 and the shape of t e upper and lower facesof said transom enables it to tilt and be set against the single outer bead 85, although a stationary transom can be used, and in such case an inner bead can'be used, such as is Shown in dotted lines in said Fig. 7.

The head for the transom 82 is substantially like the head 3, and a plate 86'is used above and against the channel section 6 of said head, as well'as like side plates against the like section of the jambe 2, so that such plates will then be between said sections and the masonry or brick-work A in this construction and can extend outwardly beyond said head and jambs to support said wall and be varied in widthaccording to the thickness of said wall. The side plates 86 are preferably formed of steel and are rovided with iianges 87 thereon with which screws- 87 -throughthebodiesot the sill sections $7 an 777 4are adapted` to engage for the holding of these' parts t ether.

It will thus be seen t atas-rny improved window frame and sash has its main parte formed of cast metal and rolled steel, it will occu y such a small space in the thickness of the uildin walls that thethickness offthe masonry or riche-work throu hout suchfwalls will be reducedto considerab y less thickness than in the ordinary window,-const:rnctions, while the frame or easinglis solcpnstructed, that with the progressgof, suehmasonry; or brick-work on a building',l the Afrar'n'e, or veasing will be built :in as suchwork proceeds, and the weight and strength/in, `thsfcon-V structionl of frame or casingv provides Vthe necessaiy support fonthe mason work across the win ow spansor openings.

It will lso be seen that the main members of the center mullion being formed `of east metal and rolled steel it Will provide a stiii'en-` ing support in the center or'A the window opening, as Well as forming a part oi the window frame or casing, while the construction of the sash will enable vthe same to travel freely through its two forms of bearings, by reason of said bearings engaging with` three sides of the sash and within the pulleys, and the bearing within the hollow portion of the sash being concealed will not be exposed to the elements. The sash at all its points bears against the balls or rollers and not against the guides, thereby allowing clear pla and avoiding. binding. The form ofthe sas ernployed is more substantialand more compact than the ordinary constructions by reason of their main members being formed of east metal, and in itself is of such section as to form stops for ythe glass lights, thereby doing away with separate pieces to be attached to the sash. for such stops,v4 as in such ordinary constructions.

Various other forms of sashes can.` be used -with such frames and other forms of frames* can be used with such sashes, while various modifications and changes in the design and construction of both my improved window frame and sash may be resorted t9 :without departing from the spirit of the invention, or sacrificin any of its advantages What claim as m invention,l and desire to secure by Letters atent, is: l
